Robert Del Tredici
Robert Del Tredici is a Canadian photographer, artist, and activist, who documented the impact of the 1979 Three Mile Island accident on the community. His first book of photographs and interviews, ''The People of Three Mile Island'' (Sierra Club Books, 1980), was a social critique of nuclear power. His second book, ''Slaves At Work in the Fields'' (Harper & Row, 1987), discussed the US nuclear weapons industry and won the 1987 Olive Branch Book Award for its contribution to world peace. He founded thAtomic Photographers Guildin 1987 along with photographers Carole Gallagher and Harris Fogel. Del Tredici has a Bachelor of Arts in Philosophy, and a Master of Arts in Comparative Literature. For many years he taught Photography and the History of Animated Film at Concordia University in Montreal, and he previously taught at Vanier College.

Three Mile Island Accident
The Three Mile Island accident was a partial meltdown of the Three Mile Island, Unit 2 (TMI-2) reactor in Pennsylvania, United States. It began at 4 a.m. on March 28, 1979. It is the most significant accident in U.S. commercial nuclear power plant history. On the seven-point International Nuclear Event Scale, it is rated Level 5 – Accident with Wider Consequences. The accident began with failures in the non-nuclear secondary system followed by a stuck-open pilot-operated relief valve (PORV) in the primary system that allowed large amounts of nuclear reactor coolant to escape. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident (LOCA). The failure of operators is attributed to the out-of-the-loop performance problem. TMI training and procedures left operators and management ill-prepared for the deteriorating situation. During the event these inadequacies were compounded by design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Power
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear ''fission'' of uranium and plutonium in nuclear power plants. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Generating electricity from fusion power, ''fusion'' power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Olive Branch Book Award
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus ''Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption are gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concordia University (Montreal)
Concordia University ( French: ''Université Concordia'') is a public research university located in Montreal, Quebec, Canada. Founded in 1974 following the merger of Loyola College and Sir George Williams University, Concordia is one of the three universities in Quebec where English is the primary language of instruction (the others being McGill and Bishop's).

Anti-nuclear Movement In Canada
Canada has an active anti-nuclear movement, which includes major campaigning organisations like Greenpeace and the Sierra Club. Over 300 public interest groups across Canada have endorsed the mandate of the Campaign for Nuclear Phaseout (CNP). Some environmental organisations such as Energy Probe, the Pembina Institute and the Canadian Coalition for Nuclear Responsibility (CCNR) are reported to have developed considerable expertise on nuclear power and energy issues. There is also a long-standing tradition of indigenous opposition to uranium mining.Lutz Mez, Mycle Schneider and Steve Thomas (Eds.) (2009).

Kenji Higuchi
has been a professor of photography at several institutions in Tokyo, and an instructor at the . He is the eldest son of a farmer and at the age of 24 took up photography after viewing Robert Capa's famous war photos. He published some of the first images of nuclear workers toiling inside a reactor in 1977. Higuchi's photos mainly depict people and situations associated with nuclear issues and he won a Nuclear-Free Future Award. Higuchi has documented the struggles of radiation victims and, over a half-century, has written 19 books, including ''The Truth About Nuclear Plants'' and ''Erased Victims''. Since the 2011 |
A Nuclear Crisis In Historical Perspective
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Three Mile Island Accident Health Effects
The domino effects of the 1979 Three Mile Island nuclear accident are widely agreed to be very low by scientists in the relevant fields. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray and maximum local exposure equivalent to less than a year's background radiation. The U.S. BEIR report on the Biological Effects of Ionizing Radiation states that "the collective dose equivalent resulting from the radioactivity released in the Three Mile Island accident was so low that the estimated number of excess cancer cases to be expected, if any were to occur, would be negligible and undetectable." A variety of epidemiology studies have concluded that the accident has had no observable long term health effects. One dissenting study is "a re-evaluation of cancer incidence near the Three Mile Island nuclear plant" by Dr Steven Wing of the University of North Carolina. In this study, Dr Wing and his colleagues argue that earlier findings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
